Procedure

A mixture of methyl N-[2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-yl]-beta-alaninate and a solution of ammonia in methanol (7 N, 10 mL) was heated with stirring at 85° C. in a sealed tube overnight. The resulting mixture was concentrated in vacuo. The residue was purified by preparative HPLC to afford 59.2 mg of the desired product as a solid. MS obsd.
